MACHINERY FOB, COMBING WOOL.

Specification of Letters Patent No. 9,856, dated October 26, 1852.

To all whom 'it may concern:

Beit known that we, SAMUEL CUNLIFFE LISTER, of Manningham, near Bradford, in the 'county of York, and GEORGE EDMoND DONISTH'ORPE, of` Leeds, in the same county, England, manufacturer, have invented or discovered new and useful Improvements in Machinery for Preparing and Combing lool or Various other'Fabrous Materials; and we, the said SAMUEL CUNLIFFE LISTER and GEORGE EDMoND DoNIsTHoRrE, do hereby declare that the nat-ure of our said invention and the manner in which the same is to be performed are fully described and ascertained in and by t-he following statement thereof and the accompanying drawings, figures, and letters marked thereon.

V e have not thought it necessary to show a complete machine for combing wool as Such is now well understood. le have therefore only shown those parts thereof to which ourimprovements are applied.

Figure l denotes a plan. Fig. 2 a section. Fig. 3 a side view, and Figs. 4, 5, and 6 detached views of machinery according to our improvements.

a, a are the carrying combs which receive the wool as it is fed on them in detached port-ions by the nipping or holding machinery and as it is accumulated on these combs itis conducted forward to be drawn oft in the ordinary manner. The nipping mechanism consists of the bars 7), 7) (which alternately come into operation) the plate c', and the endless band or apron c such being made to act so as to receive the wool between them and draw portions of it from the combsfd, (7. Vhen the instruments 7), c, c', have taken a portion of wool and brought it toward the circle of combs one of the ibrush surfaces (to be hereinafter described) alternately comes into position to take such portion of wool and place it on the combs a. The various parts are driven in the following manner, e istlie main shaftof the apparatus. It receives motion by means of a strap or band acting on the drum e. Upon this shaft e are fixed the beveled pinions e2, e2, which respectively take into and drive the beveled pinions f, f affixed on the shafts fx, fx, upon which are respectively formed th@ SC-leWS f2, f2, fOr giving motion to the gills (Z as is well understood. Upon the shaft e is also aiiixed t-he pinion e3, which by means of the intermediate gear wheel e, gives motion to the toothed wheel 7)', aiiixed on the shaft of the roller or frame b2, that carries the bars 7) such bars being formed and applied thereto (as shown in the drawings) so as to be capable of sliding freely in radial directions within the cylinder frame or roller b2. They have a tendency constantly, to be pressed outward from the surface of the cylinder b2, and this by reason of the springs `7)3, which press against the inner surfaces of the said bars b, b as shown in the drawings. But the bars 7), b are controlled in their movements by means of the rims of the two plates 7), b4, which are aiiixed to the framing of the machine by means of the pillars o5. There are cam surfaces on the inside of these rims against which the rollers 7), 5G, carried by the bars 7) run and control the motion of the bars and it will be seen that each of the bars 7), 7) comes out from the surface of the cylinder or drum b2, just as (during the revolution of the roller b2) it comes around to the point where the gill combs deliver the wool. The wool is then nipped bet-Ween the said bar 7) (which for the time being is acting with theiapron c) and the apron c they traveling forward together and drawing out and detaching a quantity of wool from the screw gills. The apron c is conducted over the upper edge of the plate c, and thence over the roller c2, which receives rotary motion (so as to travel at the same surface speed as the cylinder frame or roller b2) by means of the toothed wheel b? on the shaft of the roller b2, which (wheel) takes int-o and drives the pinion c3 (shown by red lines) affixed on the axis or shaft of the roller c2. Thence the apron c passes over or partially around the guide roller c4 and down under the roller c5. The lower edge of the plate c is supported at each end in a bearing c as shown. By pressure of the apron c against it the upper edge of the plate cVL has a tendency to constantly-rest against the roller c2. But when the nip is to take place in order to detach from the giil combs a portion of wool or other fabrous material which has been brought forward by them it is necessary that the upper edge of the plate c together with that part of the apron c which for the time may be passing over that edge should be in position nearly it not directly under the bar Z) (as shown by the drawings) and thus form in conjunction with the bar 7) a means of effecting such nip. For this purpose an ear 07 is attached on each side of the plate c and made to project from each side of the machine. These ears respectively have holes in which slide respectively the ends cx, 0X of the eccentric rods cs, cs. The other end of each of these rods c3 embraces an eccentric 09 affixed. on the shaft e. In the revolution of these eccentrics the ends cx, c* of the rods 08, 0S slide freely t-hrough the holes formed through the cars c7, c?. But these rods just when the nip is t-o take place are arranged or made so as to draw the ears and consequently the plate c a short distance toward the gill combs. As the eccentrics revolve fart-her with the shaft e the rods cs, o8 slide through the ears and permit the plate c to move forward (with the apron) and rest against the roller c2, which roller neXt act-s with the apron in the further movements of the latter and the nipper bar As the'detached portion of w'ool or other fibrous material under operation, comes forward with the holding instruments, b, c, o the edge of such detached portion which was nipped by and between these holding instrumentsis next received on one of the brush surfaces g which are carried by the frame g. This frame g is a'lHXed to the shaft or spindle g2 which has afiixed to it the toothed wheel g3, that takes int-o and receives motion from the toothed wheel o7, see Fig. l. The brushes as the frame g moves partly around on its axis g2 takes the detached portions of the wool or other fibrous material under operation and successively depfosit them on the teeth yof the passing comb a where they are accumulated and so soon as such detached portions are brought or laid on to the combs a they are pressed down into the teeth thereof by means of the brush 7L which next or immediately afterward recedes out of the way for another portion of wool or other fibrous material to be similarly placed on the comb such first portion in like manner being pressed down into the teeth a. So on each successive portion of wool will be pressed down upon the combs a, by the brush 7L. This brush h is affixed to one end of the lever L, the other end of which is supported so as to turn upon the pin 7a2 that passes through it and the standard h3 as shown in the drawing. The lever h is connected by the rod 7b4 to one end of a lever h5 'that turns upon the shaft he and at its other end, by means of a link k7, is connected to the crank 72,8 formed on the shaft hg which 1s supported in the framing of the machine and receives motion fro-1n the shaft of the roller 02 by means of the pinion klo aixed on that shaft such pinion being caused to engage with and drive an intermediate Wheel fall, which in its turn takes into and gives motion to a toothed wheel k12 affixed on the axis zP.

7e have explained the above described parts as workino in connection with a circle of passing combs ai, but we do not always confine ourselves to that arrangement of combs as in place of their being circular they may be arranged in either straight elliptic or wire lines. And in placeof there being moving combs they may be fixed and only removed when charged or filled with wool, such wool to be afterward drawn from them in the ordinary manner. But when a circle of teeth is employed we have found it better that the brushes g, g &c. Where they deposit their detached portions of fibrous material on the combs a should be moved or made to conform on their rubbing surface to the figure of the passing combs; while in taking detached portions of fibrous Inaterial from between the holding inst-rument they should be straighton their rubbing surface. For this purpose we have formed each of the brushes g in three portions and so as to have motion given to them in the revolution of the frame g in the following manner, each of the outer portions of the brushes g turns upon a center g4. The two center ones are connected together by means of plates gx gX one on each side as shown in Fig. 4 and they have also other plates or bars g5 g5, the ends of which project be ond the length of such middle portions 0 the brushes g and have slotted openings formed through them for the purpose of receiving respectively the headed pins or screws g6 by which the outer and center portions of each of the brushes g are connected together any motion given to the center portions will control the positions of the end portionsone of the brushes f/ is constantly pressed into a straight line bymeans of the spring gT while the other has a constant tendency to be drawn into a curved line, g8 is a lever turning upon the center g9, and carried by the frame g. One end of this lever presses against the center portions of one of the brushes g. The other end of this lever g8 passes into the course or cam Groove formed in the plate g1". This course 1s formed as a cam course to give motion to the lever ga so that when the brush against which this lever g8 works may be pressed into a straight line (at the time of its passing the apron c) the other brush will have a curved form given to it as seen in Fig. 4. When during the revolution of the frame g the brushes point directions in which they are shown the lever g8 will by the cam groove be brought into such a position that the spring g7 will be allowed to act so as to press the brushes in sections g (against which that spring acts) into a straight line with each other.

)Ve would here state that although we have shown and described screw gill combs, as those through which the fibrous material is to be previously conducted, and from which it is to be subsequently withdrawn in detached portions and fed into teeth of other combs or instruments, we do not conline ourselves thereto as the same may be varied without departing from our invention, and in withdrawing the detached portions of wool or fibrous material (by the nipping or holding instruments) from the teeth employed, the noil or refuse will be left in the teeth used excepting such as the nippers or holders may have hold of. But in the continuous movementof the gills or gill combs the noil or other refuse left from the portion last detached will be brought forward to be taken hold of at the next nipping, and such nipped portions containing the refuse will be laid upon the combs with the noil or other refuse. The cleansed or drawn out ends of all such detached portions of wool or other brous materials (which have been drawn through the gill or other combs used) will, when on the combs, a, be projecting from those combs, so that in the drawing the wool, or other fibrous material under operations, from the combs a the noil which was in the ends of those accumulated portions of wool or other fibrous matters, will be left in the said combs.

Having thus set forth our invention we would have it understood that what we in which the revolving brush that takes the w'ool from the nipping apparatus and conveys it to and lays it upon a circular band or belt of upright teeth L is constructed and operated the same consisting in making the said brush in sections (g4, g4, g4) and combining therewith mechanism by which not only a range of these sections can be thrown into a straight line wit-h each other, but another and opposite range can be thrown into a curved or bent line, as hereinbefore described the said mechanism for effecting the movements of the sections of the ranges being as hereinbefore explained and as represented in Fig. 4 of the drawings.

In testimony whereof we have hereto set our signatures this sixteenth day of April in the year of our Lord one thousand eight hundred and fifty one.
